“…Yang et al reported that the conductivity of PVA solutions was enhanced with increasing content of gold nanoparticles in solution. 34 It is known that the charge density of a solution increases with addition of metal nanoparticles. The resultant polymer nanocomposite solution forms thinner electro-spun fibers because stronger elongation forces are imposed on the ejected jets in the electric field.…”

Polystyrene/gold nanoparticle (PS/AuNP) composite fibers were fabricated using an electrospinning technique. Transmission electron microscopy (TEM) showed that the diameters of the naphthalenethiol-capped gold nanoparticles (prior to incorporation into the PS fibers) ranged from 2 to 5 nm. UV-vis spectroscopy revealed the surface plasmon peaks of the gold nanoparticles centered at approximately 512 nm, indicating that nano-sized Au particles are well-dispersed in solution. This was consistent with the TEM observations. The electrospun nanofibers of PS/AuNP composites were approximately 60-3,000 nm in diameter. The surface morphology of the PS/AuNP composite and the dispersability of the Au nanoparticles inside of PS after electrospinning process were investigated by SEM and TEM. The thermal behavior of the pure PS and PS/AuNP nanocomposites and fibers were examined by DSC.

“…Gold nanoparticles were prepared by trisodium citrate reduction of HAuCl 4 in PVA ethanol solution (30% v/v) (26,27). Briefly, 2 ml of 2% w/v trisodium citrate was added to the PVA solution mixture and stirred at 95-100°C, and then 0.7 ml 1% w/v chloroauric acid aqueous solution was added to this mixture where the color of the solution changed to blood red.…”

Novel Vitamin and Gold-Loaded Nanofiber Facial Mask for Topical Delivery

et al. 2010

Abstract. L-ascorbic acid has been widely used in cosmetic and dermatological products because of its ability to scavenge free radicals and destroy oxidizing agents. However, it is chemically unstable and can easily be oxidized. The current cosmetic facial masks available in the market are pre-moistened, which means that the aqueous fluid content of the mask may oxidize some of the unstable active ingredients such as ascorbic acid. This work presents an anti-wrinkle nanofiber face mask containing ascorbic acid, retinoic acid, gold nanoparticles, and collagen. This novel face mask will only be wetted when applied to the skin, thus enhancing product stability. Once moistened, the content of the mask will gradually dissolve and release the active ingredients and ensure maximum skin penetration. The high surface areato-volume ratio of the nanofiber mask will ensure maximum contact with the skin surface and help to enhance the skin permeation to restore its healthy appearance. Electrospun fiber mats may provide an attractive alternative to the commercial facial cotton masks.

“…In the previous research, pure random electrospun nanofibres tended to display enhanced mechanical properties in polymer matrix [6,7]. Recently, polymer nanofibres containing carbon nanotubes [8][9][10][11], clay [12,13], ceramics [14] and metals [15,16] have been fabricated by several research groups. At the same time, research on nanofibre assemblies explored various structures and methods, including aligned fibres [17][18][19][20], patterned fibres [21,22], and helical fibres [23].…”

Abstract.A facile way for alignment of carbon nanotubes in macroscopic polymer matrix was developed by combining electrospinning and in-situ polymerization. The approach is based on the formation of nanofibre scaffolds with wellaligned arrays, which is filled with carbon nanotubes (CNTs). CNTs will be well aligned in macroscopic polymer matrix when the aligned nanofibre scaffold containing CNTs has been incorporated into the poly(methyl methacrylate) (PMMA) matrix by in-situ polymerization. We demonstrate that this scaffold approach is broadly applicable and allows for the fabrication of nanocomposites with accurately aligned nanofillers. The results presented in this report show that the approach is ideal by using polyacrylonitrile (PAN) nanofibres as a scaffold of multiwalled carbon nanotubes (MWNTs), and PMMA as the macroscopic polymer matrix. The tensile strength (7.2 wt% MWNTs/PAN nanofibres loadings) reaches 48.61 MPa, 87% higher than that pure PMMA, and the tensile modulus is increased by 175%.
